Hi, banking sites can sometimes be troublesome, but try turning off 'Enhanced Tracking Protection' for that site (and if necessary, on each stage of the login process) by clicking the shield icon at the left-hand end of the address bar while the page is loaded - [[Enhanced Tracking Protection in Firefox for desktop]]. Try deleting ALL references to the website in question. To do that, open the 3-bar menu > Library > History, then click the Show All History link at the bottom of the list to open the History-library window. Search for the website you want to clear by typing its name in the Search History field in the top-right corner. Now in the search results, right-click on the site you want to remove, and select Forget About This Site. '''(Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed).''' Give it a few minutes to complete the deletion, then try the site (not from an old bookmark) again. More - [[Delete browsing, search and download history on Firefox]].
